Thanks for the explanation, so IIUC RSLs are binary files that are
signed and hosted on http servers. Apache does have a mirroring
structure (see for example), so hosting
is not a problem.

Files released by Apache projects are usually signed using detached
PGP signatures, see - a
release manager signs the files, and the release is backed by a PMC
vote, making it an act of the foundation.

In the case of RSLs I assume signatures are checked by the client,
what are the requirements for that?
